Question

under anaerobic conditions, the major metabolite produced in the muscle for export is which of the following? group of answer choices glucose lactate pyruvate fructose alanine

Answer 1

Under anaerobic conditions, lactate is the major metabolite produced in muscles for export, later to be recycled in the liver.

Step-by-step explanation:

Under anaerobic conditions, such as during intense exercise when oxygen supply is limited, the major metabolite produced in the muscle for export is lactate. This is because the breakdown of glucose through glycolysis produces pyruvate which, in the absence of sufficient oxygen, is converted to lactate. Lactate can then be transported to the liver where it can be converted back to glucose via the Cori cycle. This process of lactate production and recycling is crucial for maintaining energy production during anaerobic conditions.
